Why does my Dubai apartment smell damp after rain and what should I do?
Every time it rains in Dubai my apartment gets a musty damp smell, especially in the bedroom near the window. There are no visible water stains on the walls but the smell is really unpleasant. Is this a waterproofing issue and who is responsible for fixing it?

A damp smell after rain in a Dubai apartment almost always points to a waterproofing failure in the building envelope. The most common causes are a failed roof membrane (especially in buildings over 10 years old), cracked external render allowing water ingress, poorly sealed window frames or balcony doors, and blocked drainage pipes.
Critically, if you are in an apartment, the source may not be on your floor. Water travels through concrete slabs and can appear in a unit several floors below the actual leak. This makes it essential to involve building management, not just your landlord.
For tenants, report the issue to your landlord in writing immediately. Keep a copy. Under Dubai tenancy law (Law No. 26 of 2007), structural waterproofing issues are the landlord's responsibility. If they do not act within 30 days, you can escalate to RERA via the Dubai REST app.
For villa owners, a waterproofing specialist will carry out a moisture survey using thermal imaging or moisture meters to pinpoint exactly where ingress is occurring. Never let a contractor start remedial work without this diagnosis first.
Act quickly. A small waterproofing failure left untreated becomes a major structural problem and mould risk within months in Dubai's climate. The cost of fixing a small crack is a fraction of the cost of repairing water-damaged ceilings and walls.
